:EXTernal Trigger Commands
Control the input characteristics of the external trigger input. See
"Introduction to :EXTernal Trigger Commands" on page 266.
Introduction to
:EXTernal Trigger
Commands
The EXTernal trigger subsystem commands control the input
characteristics of the external trigger input. The probe factor, impedance,
input range, input protection state, units, and bandwidth limit settings
may all be queried. Depending on the instrument type, some settings may
be changeable.
Reporting the Setup
Use :EXTernal? to query setup information for the EXTernal subsystem.
